Habit | Herbs, perennial, 0.8–2.5 dm; from a woody caudex; with slender, branching roots. | Herbs, perennial, 0.5–1.6 dm; from a woody caudex; with a taproot. |
Stems | few to many, decumbent-based to erect, unbranched except for short, leafy axillary shoots, hairs sparse, spreading, medium length to long, soft and dense, short to medium length, stipitate-glandular. |
few to several, erect to ascending, decumbent at base, unbranched except for small, leafy axillary shoots, hairs weakly spreading to appressed, ± matted, especially distally on stem, fairly short and sparse proximally, longer and denser distally, soft, eglandular, becoming woolly, often obscuring surface. |
Leaves | green or gray-green to purple (sometimes different on stems of same plant), linear-lanceolate, distal sometimes broadly lanceolate, 0.5–4 cm, not fleshy, margins plane, involute, 0(–3)-lobed, apex acute to acuminate; lobes ascending, linear to narrowly lanceolate, apex acute to acuminate, rarely obtuse. |
gray with hairs, surface green to purple, linear to narrowly lanceolate, 1–3.8 cm, not fleshy, margins plane, sometimes ± wavy, involute, 0–3-lobed, apex acute; lobes ascending-spreading, linear to narrowly lanceolate, apex acute to obtuse. |
Inflorescences | 2–12 × 1–3 cm; bracts greenish to dull purplish or brownish throughout, or proximally greenish to dull purplish, distally pink to purple or magenta, rarely white, ovate, broadly lanceolate, or oblong, (0–)3–5-lobed; lobes ascending to erect, lanceolate, medium length, arising above mid length, apex acute to rounded. |
2.5–6 × 1–2.5 cm; bracts greenish to pale yellow-green or very pale, dull purplish throughout, lanceolate to oblong, (0–)3(–5)-lobed; lobes usually ascending, linear, medium length to long, arising near mid length, apex acute. |
Corollas | slightly curved, 16–21 mm; tube 10–16 mm; abaxial lip sometimes partly exserted, beak usually exserted; beak adaxially green, 6–7 mm, margins red; abaxial lip greenish, inflated, pouches 3, shallow, central pouch shallowly grooved, visible through front cleft, 3–4 mm, 60% as long as beak; teeth erect, violet-purple or pink, 1–2.5 mm. |
straight, 18–25 mm; tube 3.5–5.5 mm; subequal to calyx, or beak and sometimes abaxial lip exserted; beak adaxially yellow, 6–8 mm, hairs moderately long, matted on midline, very short-glandular on sides; abaxial lip green, inconspicuous, slightly pouched, 3.5–5.5 mm, 60–90% as long as beak; teeth erect, white or yellow, 0.5–3 mm. |
Calyces | proximally brown or dull magenta, sometimes green, distally colored as bracts, 12.5–18 mm; abaxial and adaxial clefts 5.5–10.5 mm, 40–65% of calyx length, deeper than laterals, lateral 0.5–2 mm, 5–15% of calyx length; lobes oblong, apex rounded. |
yellow, color mostly obscured by whitish hairs, 15–22 mm; abaxial, adaxial, and lateral clefts (5.5–)7–12 mm, 35–55% of calyx length, often appearing shorter because matted hairs stitch proximal part of clefts shut, all 4 clefts subequal; lobes broadly linear, apex acute. |
Stigmas | greenish to deep bluish purple. |

Discussion | As delimited here, Castilleja lemmonii is endemic to the highlands of the Sierra Nevada in California and in adjacent Washoe County, Nevada. It differs from C. lassenensis, a plant of volcanic highlands around Mt. Lassen, which has consistently white corollas. Corollas are usually pink to purplish in C. lemmonii. Castilleja lemmonii also tends to have somewhat shorter lateral calyx clefts, though the two species overlap slightly in this character.

Castilleja nivea is endemic to alpine habitats in the mountains of northwestern Wyoming and adjacent Montana. It forms occasional hybrids with C. pulchella, which often shares its habitat, as on the Beartooth Plateau in northwestern Wyoming.
